The Ultra Selle Pied begins in Conty, Somme, billed by the local walking association Conty Selle Pied as the department's first ultra-walk. This March event is for solo walkers and families, offering five route choices instead of a single fixed distance. A timed bib system adds a competitive element, but the format remains more of a mass walking challenge than a runner-only ultra.
The routes all commence in Conty. The Family Walk covers 6 km with over 100 m of elevation gain, while the 11 km and 21 km routes each remain under 100 m of gain. Aid stations are available on the course, participants are asked to bring an eco-cup, and all finishers will receive a souvenir gift. The organizers previously hosted Rando'Truch, a unique hike centered on a fondness for potatoes, indicating that the Ultra Selle Pied maintains a deliberately playful local character despite the timed bibs.
